------- Comment #2 from pinskia at gcc dot gnu dot org 2008-12-12 01:46 ------- No GCC 4.3 and above is doing the correct thing. This code is invalid but no diagnostic is required by the C++ standard.
See <http://gcc.gnu.org/gcc-4.3/porting_to.html>: Name lookup changes GCC by default no longer accepts code such as template <class _Tp> class auto_ptr {}; template <class _Tp> struct counted_ptr { auto_ptr<_Tp> auto_ptr(); }; but will issue the diagnostic error: declaration of 'auto_ptr<_Tp> counted_ptr<_Tp>::auto_ptr()' error: changes meaning of 'auto_ptr' from 'class auto_ptr<_Tp>' The reference to struct auto_ptr needs to be qualified here, or the name of the member function changed to be unambiguous. template <class _Tp> class auto_ptr {}; template <class _Tp> struct counted_ptr { ::auto_ptr<_Tp> auto_ptr(); }; In addition, -fpermissive can be used as a temporary workaround to convert the error into a warning until the code is fixed. Note that then in some case name lookup will not be standard conforming. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38501
